Inventory Window

Radionuclide source quantity and assay data is maintained in the SQL database file PSdatabase.sqlite which is located in Plaque Simulator's master data folder.

The inventory window is accessed by clicking the Source button in the Plaque Window

The radio buttons in this window select between Show only for which only inventory entries of a particular source model (e.g. I-125 IAI-125A) are listed in the table, and Show All for which all inventory entries for all source models are listed (for display and editing purposes only).
To create a New entry:
1. Select Show only.
2. Select a source model from the menu. At startup, this menu will default to the source model selected in your PS6 preferences.
3. Click the New button.
A new entry will be created. It will be named for the current patient and will have a sufficient number of sources for the currently active plaque. The source strength will be initialized to 1.0 (mCi or U) calibrated to the implant date of the active plaque. Therefore, it is more efficient to have previously entered the patient name, set the implant date, and selected a plaque before creating a source inventory. You may optionally edit these parameters at a later time.
To select an inventory entry with which to load a plaque, single-click on it in the displayed table.
To edit an inventory entry, first select it in the table and then click the Edit button or double-click in the list.
Sources are removed from the inventory as you install them (e.g. by loading the plaque or clicking on an empty slot in the plaque), and are returned when you remove them (e.g. by unloading the plaque or clicking on a filled slot in the plaque) or change to a new plaque.
The power level icons provide a graphic indication of remaining source strength on the current implant date (as set in the Rx Window) and future source strength.
Plaque Simulator may automatically create new inventory entries when returning sources to the inventory if it can't find a matching entry in the database.
Click in a column title to re-sort the table.

To delete a single entry:
1. Select an inventory entry in the table. The delete button title will reflect the database ID of the selected entry.
2. Click the Delete button
To delete multiple entries simultaneously:
1. Enable multiple selections using the checkbox to the left of the Delete button.
2. Select one or more entries from the table using the usual MacOS selection methods:
  - Single-click to select an individual entry in the table.
  - To select multiple entries from the table:
    - Shift-click to contiguously extend a selection. For example, single-click on the first item you want to select. Then hold down the Shift key and click on the last item you want to select. Everything between the two clicks will be selected.
    - Command-click to selectively toggle individual entries in the table.
  The delete button title will reflect the number of selected entries.
3. Click the Delete button. You will receive a modal alert to reconfirm that you wish to delete multiple entries.
4. Enable multiple selections using the checkbox to the left of the Delete button.
5. Highlight seeds from selected inventory when enabled, sources in a plaque that came from the currently selected inventory (or set of selected inventories when multiple selections is enabled) will be highlighted with a faint purple tint in the Plaque and Setup windows. Note: selecting a seed or set of seeds in the Plaque Window (set the cursor to selection mode) will select the inventory entry that it came from here in the Inventory Window.

Typically, you will create at least one New entry for the currently planned patient and plaque. You will need to create additional new entries for the different strengths used in an intensity modulated plaque. This example illustrates a plaque that uses 21 seeds and 2 seed strengths, (8) 1.5 mCi seeds in the perimeter ring and (13) 1.0 mCi seeds elsewhere in the manner of a classic Paterson-Parker (aka Manchester System) surface or planar implant.

As a convenience, you can also Clone entries that have locked calibrations in order to simplify reusing existing seeds for subsequent patients.
